l Specification forming part of Letters Patent No. 124,721, dated March19, 1872.

To all whom t may concern:

Be it known that I, HENRY CLEMENT, of Rising Sun, Ohio county, State ofIndiana,

have invented a new and useful Improvement in Wagon-Jacks. A

To enable others to make my wagon-jack vI will proceed to describe itsformation, referrin g to the drawing of the several parts of same heretoattached and forming part of this specication.

Letter A represents a perspective drawing -of my wagon-jack as it standsready for use,

of these legs bear against a center bolt,`D,

running through and holding the uprights B B together; they are held andhindered from extending beyond the bolt by bearing against it andagainst each other so that they cannot .spread out further. The centerbolt D, held by the screw h, has attached to it a movable stay or bracerod, G, which extends over and acts on the lever E at the notches g g g,made at certain required distances, and so adjusted as to suit theheight of the Wagon, dray, or other vehicle, holding the lever in therequired position. E is the lever for raising the vehicle when the wheelis required to be put on or taken oli', and acts between the uprightpieces B B at e e e e and held there by amovable iron pin, F, runningthrough the upright pieces.

What I claim as my invention is- A Wagon jack consisting of two uprightpieces, of wood or iron, havingJ movable legs extending laterally, and aliever held in position by a stay or brace rod acting in notches,arranged to act substantially as and for the purpose hereinbet'ore setforth and described.

In testimony that I claim the foregoing invention I have hereunto set myhand and seal this 23d day of January, 1872.
